Fitting Exponential Models to Data · Review Exercise 69

Determine whether the table could represent a function that is linear, exponential, or neither. If it appears to be exponential, find a function that passes through the points.

$$\begin{array}{ccccc}\text{x}& \text{1}& \text{2}& \text{3}& \text{4}\\ \text{f(x)}& \text{3}& \text{0.9}& \text{0.27}& \text{0.081}\end{array}$$

Its source prints no answer for this problem, so there's nothing to check against.
